The most powerful and successful Empire
Their Praetorian Guard and Centurion soldiers even rivaled Spartans in fighting skill.
At it's greatest extent, their territory was 2,300,000 sq.mi. Stretching throughout most of Europe
, as well as Northern Africa
, and conquered much of western Asia
Collapsed only because of lack of money to fund the enormous size of its almost undefeated Army
Should NOT be confused with The Holy Roman Empire.
The Roman Empire's influence upon the law, culture, technology, arts, religion, government,language, military, and architecture of civilizations that followed continues to this day.
